There is provided a process for the preparation of an optically active carboxylic acid or an optically active carboxylic acid amide wherein a carboxylic acid amide having an alpha-carbon substituted with a heteroatom group is enantioselectively hydrolysed in the presence of an enzyme obtainable from Pseudomonas fluorescens to give an optically active carboxylic acid or an optically active carboxylic acid amide. The carboxylic acid amide is preferably a carboxylic acid amide of formula (1): wherein R1 and R2 each independently are hydrogen or a substituent group; and R3 is an optionally substituted heteroatom group; provided that R1, R2 and R3 are different, and the carboxylic acid is preferably a carboxylic acid of formula (4): wherein R1 and R2 each independently are hydrogen or a substituent group; and R3 is an optionally substituted heteroatom group; provided that R1, R2 and R3 are different such that * is a chiral centre.
